The diagnostic utility of contrast echocardiography in patients with refractory hypoxemia.

Abstract:

:Three illustrative cases of refractory hypoxemia in adults are presented. In two cases contrast echocardiography was invaluable in establishing the diagnosis of a true anatomic right to left shunt, as well as in localizing the shunt to an intracardiac or extracardiac site. In the third case true anatomic right to left shunt was excluded by means of contrast echocardiography. The pathophysiology of hypoxemia is discussed with emphasis on the potential diagnostic utility of contrast echocardiology in patients with refractory hypoxemia. A diagnostic flow chart is proposed.

  • Response of high-sensitivity C-reactive protein to exercise training in an at-risk population.

    abstract:BACKGROUND:High-sensitivity C-reactive protein (hsCRP) is promoted as an independent predictor of atherosclerotic risk. In addition, cardiorespiratory fitness is inversely related to hsCRP in single-sex cross-sectional analyses. Our objective was to determine if modulating fitness with exercise training imposes changes...
